Intermolecular Forces in Covalent Compounds


Intermolecular forces are the forces of attraction that exist between covalent compounds holding them together. There are three different types of different strengths.

Covalent bonds are very common in non metallic compounds and elements. But also very common in simple covalent compounds is the concept of the intermolecular force. Intermolecular forces exist between simple covalent molecules (and also giant covalent molecules in Graphite). It is not to be mistaken with the actual bond. The bond of compound will be covalent, ionic or metallic and this is called the intramolecular bond, the bond between the atoms. But an intermolecular force is the weak attraction that exists between two different covalent molecules.

There are three types of intermolecular force each with different strengths and also different organizations.

Terms in section
Intermolecular forces

Intermolecular forces are temporary interactions between ions, atoms or compounds that are not considered to be sharing electrons.

Simple covalent

Simple covalent bonded compounds that have low melting and boiling points and weak intermolecular forces. Simple covalent compounds share a pair of electrons and there are not many atoms bonded together.

Giant covalent

Giant covalent structures is the term used to describe large non metallic strucutres that are made of many covalent bonds


Intramolecular is the term used to describe the bond between the atoms such as covalent, ionic or metallic
